PROCESS OF DESICCATING, DISTILLERY-SLOP.

Specification of Letters l atent.

Patented May 24., 1910.

Application filed May 10, 1909. SeriaLNo. 495,163.

To all whom it may concern:

Be it known that we, EDWARD H. BRINK- MANN and HUGO O. WENTE, citizens of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Processes of Desiccating Distillery-Slop, of which the following is a specification.

The objects of our invention are to provide a continuous, or practically continuous, process for producing dry feedfrom slop; to reduce the number of operations and the amount ofapparatus now required, thereby simplifying and expediting the manufacture, saving expense, and lessening the danger of deterioration of the material during the process.

Our invention consists in the process hereinafter described and claimed. v

The drawing shows in elevation, apparatus adapted to carrying out our process.

The reference numeral 1, designates a pipe through which the slop, as it comes from the distillery, passes to a screen 2 which partly separates the thin from the thick portion'of the slop, the thick port-ion passing to a continous roll filter press 3, from which it is delivered by the endless conveyer 5, to a mixing conveyer 6. The screen cloth is indicated by a dotted line 2*. The liquid which passes through the screen cloth flows through pipes 2 to a hopper shaped receptacle 3*, which also receives the liquid from the filter press. The liquid collected in this receptacle passes, through a pipe 4, to a pump 7, by means of which it is forced through a pipe 8, to the evaporator 9. The syrup resulting froni'evaporation passes through a ipe 10, to a syrup pump 11, by which it is forced through a pipe 12, to the mixing conveyer 6, in which it is mlxed. with the solids from the filter press. From the mixing conveyer 6, the mixed product passes to an elevator 13, and from the elevator through a spout 1 1, to the drier from which it is delivered, through s out 16, as the finished product.

It will e noted that the slop, as it comes from the distillery, goes directly to a screen, from which the thick portion goes to a continuous press; that the thin slop from the screen and the press goes to a pump by which it is forced into the evaporator and the resultin syrup is pumped to a mixing conveyer W ich also receives the solid portions as they come from the filter press; that the mixed product is conveyed to the drier from which it passes as finished goods; and that the material requires no handling until it passes out as finished goods.

If for any reason, the slop produces more syrup than the solids will absorb, a suitable quantity of some other granular and absorbent grain product may be fed to the mixing conveyer.

We claim as our invention:

The process of manufacturin dry feed from distillery slop, consisting in separating the thin from the thick port-ions by continuous filtering; concentrating the stream of the thin portion into a syrup by continuous evaporation; mixing the continuous stream of syrup with the thick portions of solid material continuously emerging from the filter press; and drying the mixture.
